STUDY OF THE TECHNICAL FEASIBILITY OF PRODUCTION OF HIGH PERFORMANCE CONCRETE USING AGGREGATES FOUND IN THE ITAJAÍ VALLEY REGION

ESTUDO DA VIABILIDADE TÉCNICA DE PRODUÇÃO DO CONCRETO DE ALTO DESEMPENHO UTILIZANDO AGREGADOS ENCONTRADOS NA REGIÃO DO VALE DO ITAJAÍ

Abstract

In Engineering, a large variety of materials and products enter the market every single day, however, it is
always necessary to make a critical assessment to identify what really will benefit the customer, and find what
the most appropriate technology for each case is. A search in Itajaí Valley was performed aimed to identify the
aggregates in the region, after the identification of the aggregates, the samples were brought to the laboratory
for the characterization of these aggregates and then check the viability of high performance concrete (HPC)
production using this aggregates. The theoretical referential brings definitions of concrete mixtures, additions,
aggregates, additives, binders, and other components used in production of concrete, then, indicate technical
and economic differences and advantages that exist between conventional concrete and HPC.
